 Currently an RTL locale needs to specify `$text_direction = 'rtl';` in a
 $locale.php file. In the interest of eliminating the ''need'' for
 $locale.php files, core should keep a list of RTL locales.

 `$text_direction` would remain functional, and we're not killing
 $locale.php -- just trying to cover its primary uses.

 While a simple array of RTL locales can be maintained now, there might
 reach a point where it will be easier to include locales/locales.php in
 core. (Indeed, mu_dropdown_languages() would benefit from this.) In that
 case, RTL could be read from there.
